Summary: Predicted to enable actin binding activity. Acts upstream of or within myofibril assembly. Predicted to be part of troponin complex. Is expressed in musculature system and somite. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita; distal arthrogryposis type 2B1; and intrinsic cardiomyopathy (multiple). Orthologous to several human genes including TNNI2 (troponin I2, fast skeletal type). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Data show thattnni1 and tnni2 transcripts were not detectable in the somites until 16 h post-fertilization (hpf), after which they were identified as slow-and fast muscle-specific, respectively.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
